Who could be next Aussie Test captain?

TOP CONTENDERS:

Mitch Marsh - A strong candidate to step up should the Cape Town ball-tampering revelations cost Steve Smith his job. Endorsed by Simon Katich as the next in line, Marsh is in form with bat and ball and is already WA's Sheffield Shield captain. Hasn't been back in the Test squad for long though.

Tim Paine - A steady hand with proven leadership qualities and years of experience. Potentially the safest option in the current Australian squad, although not exactly a long-term choice given he is 33.

Pat Cummins - Looks to be a natural leader and is well-regarded within Australian cricketing circles. Has plenty of time to grow into the role at 24 but would it be too much responsibility to put on the paceman's shoulders?
